Great advice Robert, thank you very much.
You are welcome.
I'm having me some serious Deja Vu!
Stay healthy Robert!
Ouch! Thanks for watching.
Thank you! Absolute best, most informative video I’ve seen yet! You are a true pro.
Glad it was helpful!
Ikr. I had same. I tried KSeal. No help. Actually shorted spark plugs. Had to replace coil packs. How hard is it to replace head gasket?
Great explanation..my radiator burst while I was at my mechanics addressing another issue. I was lucky, fixed it immediately.
Great to hear!
Thanks for the video, Rim Reaper 👍
Any time!
YOU ARE THE BEST, ROBERT!
thanks for watching.
I had NO idea this was the case. Thanks for all the awesome tips, I've learned so much from you over the years.
You are so welcome!
Thank you for such informative videos. You answered my question, I believe I have a bad head gasket. Now to decide what to do with it.
ouch
Robert.....You are such a wise man...your simple-to-follow advice to all Volvo owners is an absolute God Send!
(This problem did not apply to me.... I don't have the "White Block" Volvo)...... (Mines the V8)
But I was nodding all the way through watching that explanation.
What you were saying made absolute good sense.
We all know water boils at a higher temperature, when under pressure.... that's why the systems are sealed.
But at a normal operating temperature of the engine....you should be able to slowly open the cap....without drama.....
If not...as you so quite rightly say......you have a problem.
Brilliantly explained Robert. Take care.
Thanks for watching.
The best explaination ever !!!!!!
Thanks for watching.
Thanks this info has come in handy!
Nice
Great video, thanks! This let me know that my head gasket is still ok 👍
Awesome!
I need to try this tomorrow. Thank you Robert!
you are welcome.
@@RobertDIY head gasket on the v70 is in good condition no overflow spillage. Thanks again Robert!
Great thanks for those helpful informations 💪👍
You are welcome
Thanks for video Robert ;)

Thanks for watching 🇨🇺
Hi Robert! Im a great fan of your videos and informations. I also drive an older volvo c70 coupe from 2002 and repair it myself. Twenty years ago i have made a training to become a proffesional mechanic at a small vw and audi dealer (but the quallity of those older volvos is so much better than these vag-cars). Unlikely i cant work on this job anymore because of my haemophilian dessease. Due to that i always got problems getting proper technical informations or advice without spending money. So i have to thank you a thousand times for your great work and dedication for your videos! Please never give up! My best wishes to you from Switzerland! God bless you! 👏👏👍
Thank you very much.
Robert my names Brandy and I'm a huge fan! Was wondering if your going to be in the AZ area? I have an inherited 98 V70, with issues.. If ur traveling this way please consider, me and my volvo to do one of ur many awesome tutorials and have some Volvo FUN!
Great tip. My 93 240 has disappearing coolant
Sorry to hear that
love your instructions
thanks for watching.
from thailand im replace 850 pcv myself thk so much for your video
You are welcome
Animas: Well done.... Hope you are the envy of your pals, having a Volvo!
Love your channel 99s70
thanks
Hi Robert. Thanks for all of your vids! I think I have now a bad gasket to after 368.500km and 24 year with a lot km at the racetrack 😅.
Greetings Emiel (Netherlands)
That is possible. Stress and miles can lead to more repairs. lol ;)

Thankyou! Great explanation, Got ankther Subscriber
thanks for your support.
I don’t have a leak yet. I have an 2010 XC90 with 108k. I watch your videos as a proactive approach to maintaining my car. I’m having the water pump, pulleys, belts, thermostat, & hoses replaced (estimates $1800 to 2300), this week. I don’t want a car payment. I live in S Texas, it is already 87 @ 9 am today. I subscribe and this popped up on my feed. You’ve helped me in the importance of checking fluids all the time. This my #1 priority today. Taking the car 192 mi. to be serviced, don’t want any surprises. I Really appreciate your videos. Have a wonderful day😊
What part of South Texas are you located? I was just in the Valley for almost a week, just last week. I did that service for a guy recently for about $700. I plan to be back in the McAllen, Pharr, San Juan area next month.

Thank u I was driving with very low coolant so I added some and warm the car up 10 minutes driving so nothing spit out thank u
Great job!
Sun or snow, Robert is there for us!
👍🏾
Yeah... I thought that was brilliant....Robert out in the snow.... Explaining this stuff.... Wataguy...as they say in the US.
Thank you!
You're welcome!
My v70 was increasingly drinking coolant for years with no real change in performance. It's crazy how long these engines run on for with a compromised gasket. Now however, its popping out white smoke going down hills and boiling coolant. I did the test in your video which confirms it....so, it's sadly time to move it on. It did 195k miles, I bought it at 108k and it has been the best car I've ever owned. Thanks for the videos Robert, I'd have scrapped it years ago if it wasn't for your help. Now to look for another Volvo...
interesting. why don't you fix it and keep driving it?
@@RobertDIY I'm in the process of breaking my v50 down. What's your opinion on the repair? Is this something a new home mechanic can do??
Nice tips and tricks*!
Glad you liked it!
Thnk you it helped
You're welcome!
Just another of your excellent videos Robert, thank you. If you are ever over in Ireland, let me know. I owe you some beer!
I wasn't aware that the coolant was low and I was out in the car (2005 C70) at the weekend. As I drove up the hill, I felt pity for the guy in front who I felt had a problem with his engine. Turns out it was me. The car stalled and the smell I was getting was was from the dirt and oil residue on the overheating engine. Like you said, I got no warning. The coolant filler tank had a small crack where the pipe connects. When I opened the bottle, I found it was empty of coolant. Not a drop.
I checked the oil filler cap for 'creme' and was happy to see that it looks like the fluids had not mixed. I poured 6 liters of water into the coolant filler bottle over the next hour with just a tiny bit of hope... "Maybe it has a killer switch or something that shuts the engine down when it has no water.. And if I put water back in, it will get me home!"
So, I reckon it's exactly as you say.. combustion gasses getting into the cooling system.
But I have one question for you. I reckon that if the water has gotten into the oil, it means it will be much worse. Would you reckon that the 6 liters I put in would have gotten mixed with other fluids? Could water have gotten into the cylinders?
I can't check anything until I get the car back.
The engine was turning over but wasn't firing. I turned it over to check that it wasn't crocked, not to run it. It seemed that there was no fuel or spark as there was nothing. I have no reason to think that the fuel or spark were not getting through so all I could think was that water might have gotten into the cylinder and prevented a spark.
Many thanks,
John
Ireland
Didn't you say that no coolant transferred to the oil? 🤔
ruclips.net/video/3c3ArPfSzGY/видео.html
@@RobertDIY Yes Robert. I was wondering if the water that I had managed to get into the coolant reservoir could have crossed over after the gasket failed. I reckon not. Good news is that I have sourced a donor car with low mileage (it has a damaged roof) and I plan to swap the engine out. This option also suits because I needed a replacement steering rack and control module so I'm a happy chappie all round!
Thanks for getting back to me 👍
Thank you :)
You're welcome!
Obrigado pelo video
De nada.
Mi amigo I've been having this problem for one month and trying to understand it why is it doing that exactly did you describe on that Volvo day throws the water out my wife is doing the same thing Ivy in running it and finally I found a video they helped me you save me my car and a lot of money to spend I going to start my car and fix it I am100% that is my problem when my car thank you thank you thank you my my my friend you the best and if I say it like that comes from my heart to the best my friend
Thanks for watching.
@@RobertDIY Brillliant! Wow.... I love that choice of seasoning in any cooking. Always enhances the pot, somewhat.
Hey Robert, been enjoying and utilizing your videos for several years now. 98 V70xc with 240k miles is starting to blow tons of white exhaust. Haven't seen the oil/water combo and now I know why, as you've explained in awesome detail. She also needs front CV joints/half shafts, again, so the combo of these two issues may force me "to set her free." Sad, as it's been such a good vehicle (better than any vehicle i've owned in 40 years in the snow), but sometimes it's time to let go. Thanks so much!
You are welcome
I love you Robert💙
Thank you ma'am.
Whoa! Steady gal! Nice comment.
Thanks...Robert
G.M.
Oi...
Good morning.
U r the man !! Everybody kept trying to tell me it was a blown head gasket even the mechanic shop.. I did exactly what you said and no fluid came out.. I Am leaking fluid - sometimes but not always.. i see fuild under the front of my car - I cannot see where it's coming from . thinking maybe a pin hole in the radiator?
Maybe, could also be thermostat housing.
@@RobertDIY do u have any videos on that ? Because I use you to fix my Volvo for just about everything..I'm not exactly mechanically inclined but using your videos as guidance has been a Godsend!!
Pro! Thanks!
You're welcome!
@@RobertDIY Robert, would this also be the case in a 2003 V40?
Reminds me of the video yesterday. Is an informative and very good video. Hope the cylinder head isn't warped. If is and can be grinded down and be smooth with enough aluminum on the head are in? I think Red Baron has around 170k - 200k. If have to replace the head might be okay or replacing the engine. Not sure a used engine with low mileage would be okay? A remanufactured engine even if you did the work in a garage yourself would be a lot of work. Might need a computer to reset the computer in the car?
Yes the head is warped.
Yes I'm going to replace the head on the engine and store it.
I am replacing the engine in Red Barron. Along with a manual swap.
Yes the computer will be replaced.
Because it's not a red block? 😁🤗 Stay well my friend.
lol
Video was of high quality and easy to follow compared to others. Have a 2004 S40 that the head gasket appears to be breached - could not remove cap off of reservoir as detailed in your video. The car isn't worth repairing; is there a head gasket sealer that would work with combustion air escaping into the coolant? thank you
That stuff doesn't work well on these cars.
@@RobertDIY thanks again
Thanks for this video Robert. I have a question. At what temperature should on the fan in a 2004 s60r?
I don't know. I'd imagine between 205 - 235.
Do you have a video on how to replace the head gasket ?
Thank you very much for this. I'm trying to bring back one of these after sitting for 4 years outside. Unfortunately it's blowing a lot of white smoke no matter the temperature and I also found a pool of coolant under the floor mats so the symptoms certainly points toward headgasket at this point.
Q: When you're combusting coolant are they usually ok with milling the head and a new gasket? Meaning no cracks in the head or cylinder walls.
I've never seen cracked heads or walls from over heating.
You know your stuff
Thanks for watching.
Hi Robert! Thanks for the helpful video. Yesterday my v40 was completely fine (did the cap removal test) and today it bubbled out when I opened the coolant cap. Temp guage stayed near the lowest point the whole drive home (10 mins) but my RPM was all over the place and would jump up in Neutral. Haven't dug into it yet to see if the block or a cylinder is cracked...any idea if this is beyond repair?
If the coolant level is good the temperature in the dash should raise to normal within 5 minutes of driving. If not the thermostat is bad.
Thank you! Very helpful
Wow, nice tip! Thanks, from a C70 owner in England. By the way, do you think the same method will apply to a 2008 2.0D C70 (Ford Engine)?
No
It's a Volvo engine used in Ford's.
Hey Robert. Great video! Got a slow coolant leak after changing the radiator. Checked radiator and that appears fine. Leaks further back by the front tire back of oil pan area. Took off timing cover and after running for 5-10 minutes found a little coolant pooled in the bottom timing cover area. My guess is water pump. Any other areas i should be looking at before swapping the water pump? Any videos on timing, water pump and timing tensioner/pulley replacement? 2006 T2.5 S60
ruclips.net/video/gt9w-ZSxs9I/видео.html
I don't think I would start one of these cars with a leaking water pump.
ruclips.net/video/YpOYTVpzzic/видео.html
Hey Robert, I have a tiny amount of creamy mayo on my oil filler cap, nothing on the dipstick though. I haven’t tried the coolant cap test yet. Any thoughts please? 1997 V70.
ruclips.net/video/za8qgxDey8I/видео.html
03 S60, milky substance under oil cap. Car sat for 2 years in the past month-and-a-half the engine has blown on my girlfriend's Camry also my Nissan Frontier and now this. I have already put timing belt, alternator, water pump, idler pulleys. My next project was the PCV system. Pretty sure I have a blown head gasket. How do I know if the head is Warped. I want to attempt to fix? My main concern would be the cams and timing. You had a very informative video with Red Baron.
did you do the test I explain here?
ruclips.net/video/za8qgxDey8I/видео.html
Bob: Maybe public transport is for you.
How can I fix it si I have this coolant problem in my xc70 2004 volvo
Leaking?
I took your advice, drove it for 5-10 minutes, and she lost oil. I do not know where, the oil light came on, rattle noise are low rpm torque. I never got it to high rpms. Prior I did, she took off like a rocket. SO, I am hella confused here. I am 100% positive, I have more then enough old hoses that need to be replaced. My concern is if the engine is damaged. I did NOT get an engine check light, just a oil light before getting home. The same radiator hose broke Again, so that is a priority replacement. I hope just getting these hoses replaced keeps this car from having a leak issue, but the other concern is if the engine may have gotten damaged. I am going to do a compression test, and Leak test (if I can), and get a verification. I watched a video on pulling this head ... and well, it almost seems better to get another engine, and fully rebuild that and swap the damaged one onto the transmission and install that. and figure out what to do with the damaged engine (maybe repair that and get a good sale on that and recooperate some money.)
I don't even know what kind of car you have...
If you got an oil light, it is likely low oil pressure. Is the oil level low? If it leaks from full to low in just 10 minutes of driving, you have to be able to see where it is leaking from???
Little bit of a newer car but I have a 2006 volvo s60r. Coolant light comes on and off, a little bit of white smoke here and there. Did the block test and it wasn't good. Cracked block or head gasket?
likely bad head gasket. Also could have a cracked block sleeve.
Hi Robert! I just inherited a 99 Volvo S80 T6. This engine mysteriously looses about a quart of coolant occasionally. I fill it up and it will run for about 50 to 100 miles and do it again. I did the test you demonstrated in your video and i was able to remove the cap no problem. I’ve looked all over this car and can’t find any external leaks anywhere. Any thoughts?
Thanks, great video!
ruclips.net/video/8LcL6nw5FfI/видео.html
that's a lot of coolant leaking somewhere.
@@RobertDIY Thanks for your reply and help. I have some new information to add in hopes that it might help someone reading this in the future. So today was the first day it hit over 60 degrees in a long time in my area. This warmer temperature put more pressure on the cooling system which finally revealed where the leak is. The leak was where the heater hose connects to the snap firewall heater hose elbow fitting, the barb area was broken. Anyway when the system is under heavy pressure it would start leaking at this location, the more pressure in the system the more pronounced the leak.
hey thanks for your video .. i hope you can help with some advice ..
What about if the coolant actually IS draining periodically? and faster than you would expect.. what do you think the problem would be in that case? .. i am also not seeing any leaks of coolant on the ground under the car.. i dont really know what it could be .. but i seem to be having to replace the coolant every few weeks.. and that doesnt seem right ... anything you could suggest would be much appreciated..
its a volvo s60 2001..
thanks !
Have you checked the heater core?
If you can't find the leak, have a Volvo mechanic find before you blow the engine.
@@RobertDIY where do i check the heater core?
Dang Robert; Where did you film this at? I couldn't tell if it was snowing or raining! LOL 😅
LOL
Hi Robert DIY, I did this test and the coolant went over the top of the reservoir but then came back down again. Is this a head gasket problem? I did a combustion leak test, and it didn't find any combustion gas coming out of the coolant reservoir (the blue testing fluid remained blue). Do you have an explanation for this? Thank you for all you do for us Volvo lovers.
If it went down, it's likely good unless there is air in the system. Bring it by and I'll check it out.
Does tgus apply to the 850 TDi that had the VW 2.5 TDI 5cyl
Probably
Help??? My car has all the symptoms of a blown head gasket, but the Co2 chemical tester says there is no exhaust in the coolant. it pumps the water out, and has excessive pressure. Dash temp gauge says it's not overheating. I took the thermostat out for the test..so it's not a problem. I have tried two caps...both do the same thing. What else can cause this????
Man, I don't know. Air in the system. If you get all of the air out of the system and it still builds pressure, it likely has a bad head gasket. I don't know if all of those chemical testers are accurate. But if your coolant system is building pressure, it likely has a bad head gasket.
Hi Robert, , I own a s70, 1998 non turbo, 2.5 20v, a stuck thermostat could give same symptoms as head gasket?
I doubt it. How would the thermostat get stuck?
Hey Robert, I watched your video on the blown head gasket. I am pretty sure I have the blown head gasket you speak of. I recently installed a new radiator as the old radiator sprung a leak. Not long after I got the new radiator, I started getting the "coolant low" message. I worked out that it is possibly a blown head gasket and I am not allowed to do any more expensive repairs to my 2006 XC90 with 156k miles on the clock. I am wondering how you feel about using a "permanent" head gasket repair fluid in the cooling system? The Volvo runs like new after the initial startup where I think water is getting past the gasket into the combustion chamber and spoiling one of the cylinders momentarily. How do you feel about the quick fix for getting the car to go another couple thousand miles? Thanks Steve
I never have and never plan to use head gasket fix in a bottle.
Hey my Volvo s60r is leaking coolant close to the passenger tire, is there a line that runs there?
ruclips.net/video/8LcL6nw5FfI/видео.html
did you open the hood and look?
Question i have a 2001 S40 turbo and the car not over heating at all butt cooling is going somewhere not should where can you help
ruclips.net/video/gt9w-ZSxs9I/видео.html
If the car is loosing coolant I would consider it a "leak". You need to find the leak.
ruclips.net/video/8LcL6nw5FfI/видео.html
Hey Robert! I’ve tried doing this on my 99 v70 and my coolant level does not rise rapidly like it does on a blown car. However if I leave the cap off for a couple of minutes the level does rise to the point where it will spill over out of the coolant reservoir. Would this indicate a blow head?
probably not. If it doesn't come out in 60 seconds I would not worry about it.
Chris: No. What is happening there is that the pressure in the system cannot rise; Therefore, the temperature will rise:
(At sea level: Water boils at 100°C or 212°F .... But on a high mountain top, water will boil below these temperatures.)
This is why the system is sealed.... Seal the system. Pressure is the key. Let the pressure rise, due to heat rise, but the water boils much later.
This is the point of Roberts Video: You should be able to remove the rad/header cap.....at the normal operating range of the engine.
If not...you have a problem.
As Robert states: If it don't boil over in a minute...stop worrying! 😊
What would one expect to pay for a fix on head gasket?
between $1600 - $2600
Hi Robert I am getting rid of my 1998 v70 glt. Do you know of a good electric conversion for this Volvo.? There are way too many fixes that my v70 needs. Wish I could convert mine. Started driving a 2017 bmw i3 ev with a range extender. My Volvo would be still running if my radiator didn’t have a 3 or more leaks. Had this car many years. Great motor.
Nope.
You'd have to pioneer this trail yourself I think haha. If there is an electric P80 out there it is fully custom and one of a kind.
You are having a laugh....I hope.
Stick with the Volvo....
Just wait for the AVALANCHE of dissatisfied Green Wannabees moaning about their "super cool electric" ECars!
Simple rule: Progress is not cheap. Evolution is far slower. But cheap.
Hi Robert! So i have a 2000 Volvo S70 2.4L 5cyl none turbo. Im trying to find where my coolant leak is, and im wondering if gaskets for waterpump, manifold, head, thermostat housing itself as well as gasket, and thermostat housing cover and gasket? Ive already replaced radiator(original reason coolant issues happened), upper and lower hoses on radiator, coolant reservoir as well as upper and lower hoses and cap for that as well, and getting ready to do thermostat and thermostat sensor, but im still loosing coolant. Am i missing another hose somewhere? Is all the gaskets the next best move? Or what should my next move be to finding this leak??

Good day,mine is doing the same, engine coolant coming out, should I also have to skim my head?
No
I’m pretty sure I have a blown head gasket on my Volvo 850 but it’s also leaking coolant through the driver and passenger floorboards as well as having problems starting. Do you know if they’re all related in anyway?

What does it mean if coolant and oil mix?
that the head gasket is likely blown.
Hello I hope someone can help me I have a volvo v40 2003 2.0T when I was standing at the traffic light, fine blue smoke suddenly came out of my exhaust and smelled of oil, it still uses oil but it doesn't always smoke every now and then it could be the tubro be? Or the pcv system or a cylinder head gasket I'm desperate Thank you
Is it using oil? Does it have proper power?
ruclips.net/video/Bp4CtNaZh6U/видео.html
Does this work on any car or just these models of the Volvo
Many cars that have coolant reservoirs.
Did this test and I opened up the coolant reservoir after filling it up and driving until the car was up to temp. The coolant didn’t rush out so that’s good but my coolant still seems to be disappearing but very slowly
Any advice?
ruclips.net/video/8LcL6nw5FfI/видео.htmlsi=Hhd0WmTyNZ7DrbWV
I have a 2001 s80 t6 and the coolant comes out when warm and i open the reservoir, but only a few seconds, car doesnt get hotter than middle of the gauge, so could it be only too much water in my coolant mixture?
with the car running or off?
@@RobertDIY the car was running and i saw small bubbles, then liquid came up and out, i closed and reopened the lid, then the coolant returned to normal
What if you are mixing coolant with your oil I have a 98 V70 with 180,000 miles and I noticed it takes longer to start on a warm day than it does a cold day and I started to think it was my head gasket but now they're mixing in the oil pan
Should I stop driving it and fix it before it does any damage?
Ouch
I have a 2002 volvo v70 wagon. I recently had a little accident and cracked the radiator. I had to drive about 20 miles and it was over heating into the red. I put in a new radiator fixed any leaks tested it out and no problems. Now the next day i am having problems now the check engine light comes on
What's your question?
@@RobertDIY now my cooling fan is not coming on. Could that be just a fuse ?
HAD to drive 20 miles? What does HAD mean? A tow is cheaper than an engine. If you overheated the engine, you need to have it repaired or replaced.
Hey robert...i have this issue ..i tried the test on my 98 v70 turbo while it was at temp..i was able to slowly take off the cap slowly with coolant rising..but my sensor light is on..(the small light with the fan on it)..do u think the water pump is bad?...i tried buying a new cap from auto zone but its warped now and cant be tightened anymore...it doesnt over heat till i drive it for about 10 minutes at temp.. water pump?..new coolant tank?..
ruclips.net/video/BtdifArSU3Q/видео.html
Should not be over heating. What thermostat is in it?
@@RobertDIY had it one year and never did any major work..i.e. timing belt.. alternator...idk which therm is in it but i actually just did the test again and as it started to get a remp raise ..i started to open the coolant top and it stop..i closed it after the coolant stopped rising so i ruled out the gasket...i was thinking pump or thermostat next...the previous had a therm in the trunk but i tossed it because theres no telling if it was good..i looked like it was taken from a pull a part..
But what if there’s no other issues Tocqueville that would be signs of a bad head gasket
Keep driving I guess.
Think mine is also leaking, its coolant also loose its color after a while, perhaps that's also a symptom
I've never had that symptom
Hello Robert,
I just bought a V70r Fwd from 97 and noticed that I'm loosing coolant without knowing were. My mechanic did some kind of test with a blue liquid that turns green if I had CO2 in my coolant circuit and he didn't find nothing. But I keep loosing coolant without knowing were. He says that it can be a cracked block. Wouldn't that create CO2 in my coolant system?
ruclips.net/video/gt9w-ZSxs9I/видео.html
ruclips.net/video/8LcL6nw5FfI/видео.html
Is it possible even with the CO2 test not acusing any CO2 in the coolant system? Bcause my mechanic did this test and the color of the tester keeped the same blue (it turns green when in contact with CO2)
Hi Robert, I'm not so new to your channel but a new t5 owner. 98 c70 t5 to be precise. Hard top UK model. I had a scary moment when my thermostat failed. Stuck closed!! My temp gauge whent to the top just minutes from my home. Took the old stat out and tested it, definitely not opening, bubbles coming from it. So I knew the stat had failed. I am using a little bit of coolant now however. And a distinct smell of coolant in the cabin. I changed my pollen /cabin filter and still getting condensation on the windows. I suspect the heater core has perished and plan to change it as soon as the new unit arrives. My question is... If my engine was overheated with a stuck closed stat, would it mean I now need to source another block /head. Thanks in advance
If the head gasket is bad I would get the head checked, made true, and install a new head gasket.
What brand thermostat was it?
@@RobertDIY it was the original volvo thermostat. I plan to change the heater matrix, hopefully that will cure the problem of lost coolant and condensation in the car. It's only using minimal amount of coolant every month or so.
I've never seen a Volvo thermostat stuck closed.
@@RobertDIY I'll take a video with it in a bowl of boiling water and send you it. I was surprised myself! I did this a few times and bubbles were coming out of it, it stayed closed.
But the sensor doesn't tell me anything other than low coolant level shut off engine
That is usually the only warning.
Robert, I just commented on another video of yours. I bought a 99, non-turbo, 2.5 volvo for a great deal. I only have 500$ in a car with 150,000 miles. But it had been wrecked, when it was wrecked. It cracked the coolant reservoir. I tried to seal with with ultra Grey with no success. You were exactly right, after a about 10,000 miles I got lazy about topping it off one day because I did not want to stop on interstate in Atlanta, and I ran it too hot. I believe I screwed the head. I tried to cool it off, top it off and limp it home but by the time I pulled in the driveway I can no longer get it to run at all. Can you give me some insight on what all I may have damaged beyond the obvious head warping. And do you know if the head is the same with and without a turbo? It is the same block and head right? Just the intake will be different because of the turbo right?
Sorry to bother you, I just need some advice. Thank you robert.
The na engine is not the same as a turbo engine. Turbo engines are usually built tougher but have lower compression ratios. If your vehicle has any VVT hubs then you need to get a head or engine with the VVT hubs. If your engine does not have VVT hubs and both cam sprockets are naked geared sprockets, you can use a non-turbo engine from 94 all the way through to 99. However if your engine has coil packs on it you want to make sure that stuff is handled properly with the cams.
My guess is you warped the head and possibly warped or crack the block. You won't know that until the head is removed and you check the block to see if it's true. If the block is warped I would definitely just do it entire engine swap.
I tried this on my Volvo S70. It is leaking coolant somwhere. I could open my cap. The coolant level raised a bit, an inch maximum. Is that ok/normal?
yes ok
Thank you!
Check your Radiator and Water pump before replacing your head gasckets
Ok
Robert, 1999 Volvo V70 the fluid disappears, no back pressure doing your test, no oil mixing and no fluid on the ground. Clueless here.

does the type of coolant affect how/if the system is leaking combustion gas? My 2005 volvo v50 t5. I did this test, and I am not getting a FLOOD over like in the 1st red car. It pretty much does what the 2nd car is doing. I had the engine running, rev'd to 2k, held it there for 3 min's. Engine temp got to the middle. I stepped out with engine running, checked fluid in resivour, it looked the same. I went back and rev'd to 5k for 30 seconds. Engine temp stayed in middle mark. I went to check the resivour, slightly opened the cap to check for pressure surge, it was calm. I let the car sit, 5 min, then restarted, and I see on the resivour, which mine has two lines at the front face of the resivour, the line most closest to the engine, is the first line to break. it broke at two points, at a mate clip behind the radiator infront of the airbox. The second was from wearage rubbing of a loose air pipe bracket. It caused the clip that goes to the head, above the transmission, just right side of MAF sensor (just right below that). That clip was damaged broken. I ended up replacing the WHOLE tubing with a straight flex rubber hose to the resivour. That incident, the engine temp got 3/4 to red. I also had a low oil light flicker, which I was confused over. I was able to get the car home. She made ALOT of rattle noise, which I am believing now is from the odd fuel map that LIMP MODE provides. Once home, the OIL was completely changed, topped with 6 quarts. Drove the car, it was doing fine, then the Heater hose by the fire wall broke on the plastic connector. I did not get any warning of this, til the engine went into LIMP MODE. I had a huge power loss, the car would not rev over 2k, and had a rattle like the lifters were rattleing. I did not check closely if their was a knocking. But at Orielly, I was able to get a OBD2 reader on, and the Crankshaft sensor positon was faulting, same with knock sensor. I watched another video about sensor's, and things like water CAN cause sensor's to act inappropriately, and trigger a LIMP MODE. Now what really gets me is the OIL Low light. When I was at the store, the oil level on the dip stick was the same level as when the oil was replenished from the change.. I ended up putting another quart of oil, when I read a concern stating these engines are to have between 7.5 to 6 quarts of oil. Hmm, So I looked up to find out what level of oil causes low oil light. I heard from multiple Mech's, that Volvo's are very picky with low oil. You don't want to press long on a low oil issue. I believe that because Fife Volvo in WA state, screwed up my mother's 2004 S40, which resulted in the engine knocking. The Mech some how did not complete the oil change process, and the car was short and leaked oil. The smell nearly put my mom in the hospital. The engine at first drove fine, then a yank feel while driving, and then HUGE loss of power with a deeper rattle noise. That Dealership basically frauded my mother, then pushed to get her to by a NEW car, when the reality is they should fixed her car. We filed a complaint with Sweden Volvo, and their Rep's came and took the car into a detailed inspection. A mech at that location quit, and weeks later their Mech shop had an explosion. No surprise on that, you can smell the fumes from that shop. Story goes, a shop light switch was the cause of the spark, the cause of fumes, is obviously poor ventilation. So back to my car. After clearing those codes, the car started, and drove just like nothing happened. I am concerned of either warped head, or lightly spun baring, which will lead to a bad expensive situation. I had that happen on a 1991 Integra, did not even realize til the rattle down below got out. So I am trying to avoind causing further damage to the volvo. When I just did a start up, rev up, warm up, all systems seem ok, except for Airbag warning code. What I am concerned is a fuel smell from the resivour. I know with the Integra's, when the gasket leaks, the gasket at the combustion to coolant is where it breaks. I never had a head gasket fully break to be directly expelling/breathing from/into the engine ... What I got was that special color in the oil and coolant. I knew then that I would be in for an engine overhaul. This Volvo does not produce that odd color oil/coolant mixture, at least not yet. So my question is, beside the coolant test with the blue fluid breathing the coolant vaps. Is there an easier way to verify a blown gasket? My thoughts are compression test. I have a kit, and right am waiting for the car to cool complete, then pull the ignition coils and spark plugs. I am guessing I SHOULD see PSI around 135psi for 9:1 compression cylinder/piston. If the numbers deviate, then where it deviated is where the gasket is broken. Now for WARPED head check, how can I do that without having to take it apart and line up a straight to the block/head? Also, right now, I am running water in the coolant, not the reconmended product. Do the reconmended coolants have a sealing solution, or can I add one, or is that a bad idea?
First off I would use a Volvo class scanner to get proper Volvo codes.
Next I would verify head gasket breach by driving the car for 5+ minutes, then stopping and see if you can remove the coolant reservoir cap.
A compression test will not tell you if you have a small head gasket leak. A leak down test will.
If the head or block is warped, you will have a leaking head gasket.
I do NOT recommend head gasket leak fix in a bottle. Doesn't work well with Volvo's.
My car do this !! But never never the temp was high!! I blown my headgasket? Why?
Probably lost coolant at some point. If the sensor doesn't have coolant on it because the coolant is low it probably won't show the overheating issue and warped the head.
omg!
Yikes!
Does this also apply for diesel engines?
I have no idea.
@@RobertDIY thanks for your answer
I checked mine 2.5 TDI with a NON blown head gasket today
the is no coolant violently spraying out with a warm engine so I guess if someone has coolant spraying out with a diesel engine it's the same procedure
Thank you for all the good content and worthy information Robert
@@samkrause3514 Love your reply! As far as I am aware.... Diesels generally run cooler than petrol engines...WHY? Because of the sheer mass of the engine itself .... It "self-cools" Plus the exhaust gas temperature is a lot lower....and therefore the head temperature.
So many different factors involved.
In my time...I have found that most (NOT all) Diesel engines will run fine even if the system is not sealed.... they rarely get to boiling point.
But that is very general: Cars are a different ball game....They are engines running in a confined space.... Cooling is critical in any confined space.
With the newer models that have coolant flow through the intake manifold, would it be possible for coolant to reach the combustion chamber from there if there was a problem?
Yes
Ok, do you know what would cause that ?
Volvo 1997 V90 in the 960 body
Cool
Hey my car is having the problem you are talking about
ouch
Ig that’s mean I got to get a new head
ouch
Ym
:)
Mine def has a smell like something is burning
that would not have anything to do with a head gasket issue.
Could I use blue devil to fix the blown head gasket?
Not my ride, you can try.
@@RobertDIY what would you suggest. I just notice small amounts of white smoke from my tailpipe but around the manifold there is light white smoke there as well
@@orneshiawashington473 Oil that leaked and touched a hot spot on the engine to burn it due to blowby maybe?
And about the Blue Devil head gasket sealant, I kinda doubt it would do much to stop combustion gases from enterin the coolant chambers, ports, and expansion tank. But, it is worth a try.
